Interface Json.Schema

Enclosing class:

Json

public static interface Json.Schema

Represents JSON schema - a specific data format that a JSON entity must follow. The idea of a JSON schema is very similar to XML. Its main purpose is validating input.

More information about the various JSON schema specifications can be found at http://json-schema.org. JSON Schema is an IETF draft (v4 currently) and our implementation follows this set of specifications. A JSON schema is specified as a JSON object that contains keywords defined by the specification. Here are few introductory materials:

• http://jsonary.com/documentation/json-schema/ - a very well-written tutorial covering the whole standard
• http://spacetelescope.github.io/understanding-json-schema/ - online book, tutorial (Python/Ruby based)
